Figuring Out Edge Cases

Revision en1, by ldyllic, 2022-06-06 13:42:19

Hey, CodeForces!

I am seeking for you advice: how to improve my skill of figuring out edge cases? I have faced a couple of WA on 100+, 300+ test cases and each of the times I wasn't able to get what was that edge case by myself. Hence, I am asking you guys for an advice :)

And in particular — what is the edge case here?
